The Effect of System Architecture on Net Spectral Efficiency for Fixed Services
The authors consider the net spectral efficiencies of point-to-point and point-to-multipoint fixed service architectures for mobile broadband backhaul. The properties of mobile broadband backhaul traffic are examined with reference to a network case study. The network case study also provides measurements of the improvement in spectral utilization possible with a point-to-multipoint architecture. Considering the projected growth in mobile data consumption, they argue that the gains possible with a point-to-multipoint architecture are increasing with trends in RAN design towards high peak rates and small serving cells.
